Conduct a thorough evaluation of the soil Lab Kit for 50 students. Using ordinary soil samples and simple, easy-to-follow techniques and staining procedures, students are able to conduct a thorough evaluation of the soil. Using individual worksheets, students will: Identify the type and variety of microorganisms (soil microbes) - Calculate soil fertility by a cation exchange capacity elimination - Test and determine the pH of the sample - Correlate the soil’s pH value to soil lime requirements. Conclusions can be made concerning a soil’s ability to support plant growth. Tests are performed using either the patented CHEMPLATE or calibrated sample tubes.
